Magnetic nanoparticles (MNPs) were modified with 3-Mercaptopropytrimethoxysiline (MPTMS) and grafted with allyl glycidyl ether for coupling with beta naphtol as a method to form a novel nano-adsorbent to remove two poly aromatic hydrocarbons (PAHs) from contaminated water. The modified MNPs were characterized by transmission electron microscopy, infrared spectroscopy and thermogravimetric analy...

NPT Monte Carlo classical computer simulations were performed to study the structure and thermal equilibrium properties of Lennard-Jones clusters. Three sizes were considered in the study, with 38, 42, and 50 atoms, temperatures from 0.1 to 0.5 and pressures from 0 to 20 (in reduced units). For the three clusters we observe a discontinuity in the slope of the isotherms that corresponds to a rea...

The genotypes for calpastatin (CAST) and calpain (CAPN) loci were determined by PCR-RFLP and PCRSSCPmethods. Blood samples were collected from 200 pure-bred Zel sheep from Shirang’s Zel sheep Breeding Station located in south-west of Golestan, Iran. Extraction of genomic DNA was performed based on the modified salting out method. Based on results, two investigated loci were polymorphic an...

in this paper, a boussinesq equation is solved by using the adomian's decomposition method, modified adomian's decomposition method and homotopy analysis method. the approximate solution of this equation is calculated in the form of series which its components are computed by applying a recursive relation. the existence and uniqueness of the solution and the convergence of the propose...
